  2. American wire gauge - Wikipedia

    en.wikipedia.org/wiki/American_wire_gauge

    The resistance of copper wire is approximately ⁠ 1 ohms / 1000 feet ⁠ for 10 AWG, ⁠ 10 ohms / 1000 feet ⁠ for 20 AWG, ⁠ 100 ohms / 1000 feet ⁠ for 30 AWG, and so on. [ 5 ] : 27 Because aluminum wire has a conductivity of approximately 61% of copper, an aluminum wire has nearly the same resistance as a copper wire that is two sizes ...

  3. Knob-and-tube wiring - Wikipedia

    en.wikipedia.org/wiki/Knob-and-tube_wiring

    The conduit methods were known to be of better quality, but cost significantly more than K&T. [2] In 1909, flexible armored cable cost about twice as much as K&T, and conduit cost about three times the price of K&T. [6] Knob and tube wiring persisted since it allowed owners to wire a building for electricity at lower cost.

  4. Copper conductor - Wikipedia

    en.wikipedia.org/wiki/Copper_conductor

    An example of a copper alloy conductor is cadmium copper wire, which is used for railroad electrification in North America. [5] In Britain the BPO (later Post Office Telecommunications ) used cadmium copper aerial lines with 1% cadmium for extra strength; for local lines 40 lb/mile (1.3 mm dia) and for toll lines 70 lb/mile (1.7 mm dia).

  5. Wire gauge - Wikipedia

    en.wikipedia.org/wiki/Wire_gauge

    Wire gauges may be broadly divided into two groups, the empirical and the geometric. The first includes all the older gauge measurements, notably the Birmingham gauge (B.W.G. or Stubs) and the Lancashire. The origin of the B.W.G. is obscure. The numbers of wire were in common use earlier than 1735 when the measurements were officially defined. [1]

  6. Aluminum building wiring - Wikipedia

    en.wikipedia.org/wiki/Aluminum_building_wiring

    Also, the size of the aluminum wire needs to be larger compared to copper wire used for the same circuit due to the increased resistance of the aluminum alloys. For example, a 15 A branch circuit supplying standard lighting fixtures can be installed with either #14 AWG copper building wire or #12 AWG aluminum building wire according to the NEC ...

    Los Angeles isn’t the only city struggling with copper thieves. In Oakland , city officials removed traffic lights at a busy intersection after criminals tampered with the electricity in the system.

  8. Electrical wiring - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring

    For instance, instead of 14 AWG (American wire gauge) copper wire, aluminium wiring would need to be 12 AWG on a typical 15 ampere lighting circuit, though local building codes vary. Solid aluminium conductors were originally made in the 1960s from a utility-grade aluminium alloy that had undesirable properties for a building wire, and were ...

  9. Thermoplastic-sheathed cable - Wikipedia

    en.wikipedia.org/wiki/Thermoplastic-sheathed_cable

    This does not include the uninsulated ground wire. For instance, if the cable lists "12-2 AWG", it means there are two insulated 12-gauge wires (a black and a white wire), plus a ground wire. If the label says "12-3", this cable has four conductors—three 12-gauge insulated wires and a bare copper ground wire. [5]
